Comments:The hoses that came with the unit did not have proper adapters installed. You cannot glue an MPT-Slip adapter on a spiral hose! As a result both hoses were leaking and had to be replaced.
The sump itself, BS-2, had a pretty poor gluing job. Lots of bubbles in the seems and too much glue. I am not a structural engineer but it looks like the acrylic (at least it's cast not extruded) is too thin for this kind of a sump. 18 months later, I can see significant outward bowing in the panels, several seems have bad crazing, and one panel developed a 4 inch crack.
I never abused the sump, never dropped it, never subjected it to excessive heat or vibration.
It's very disappointing since it wasn't exactly cheap.

Comments:I wish I had gotten the larger size sump for my 90 gal tank, the volume is roughly 18 gal. My Eheim 1260 is a tight fit with the base on, but no other problems getting other components into the tank so far. Over all I am happy with my Berlin Sump.

Comments:I bought a berlin sump to go along with a 4" sock for filteration. I had to buy this because I was unhappy with my old sump that I paid $225 for. Let me tell you.. I paired this sump with a ASM G-2 Skimmer, and within a few minutes I could notice changes in my water clarity. People are right about the sock though, it is a challenge to clean. If you want to properly clean it, it's best to put it into the washer w/only bleach to get it to turn white.. and to kill any kind of bacteria caught in the filter.
The number of microbubbles is remarkably lower than the previous sump. I would recommend 1 thing... when it says "sump only" don't do what I did and buy the sock adapter.. it already has a place for the sock.. This item for the price is a really great addition to my reef.
I did notice some cloudiness within the first 2-3 days of hooking it up.. so rinse the sock before you use it.. either way I don't think that is preventable.

Comments:amazing results after adding this product to my tank. Maintence is much easier than the homemade one I had. I did have a bit of trouble getting it to fit in my 120's stand. I had to remove a brace to get it to fit, but overall it is a great product. always go big with a sump :)

Comments:i was done with my HOB skimmer and will never go back after plumbing my first sump. a little overkill for my tank, but you can't argue with the results. enough room for some extra rock and protein skimmer. definitely wish the smaller bs-1 had bulkhead the bs-2 has on the return side, otherwise it would have been 5-star.

Nice sump!

Comments:Its big enough to fit all my gadgets (skimmer, calcium reactor, heater and probes), and has nifty ports to connect hoses & the filter sock to. I drilled a bulkhead on the exit side, which works great (connected an Iwaki 30RLXT pump for the return). I'm running this under a 90 gal tank. So far, so good! I've got a shorter cabinet, and this unit fits under with room to reach the skimmer.
